When the population variance is unknown, the appropriate test statistic to used is
t-test
Sir!
Yes, Bryan!
In a z-test, the sample is assumed to be normally distributed. A z-score is calculated with population parameters such as population mean and population standard deviation.
-The population standard deviation is know
The population is normally distributed.
The sample size is large (n30)
a z-score is calculated with population parameters
meanwhile like a z-test, a t-test also assumes a normal distribution of the sample.
When the variance is known and either the distribution is normal or sample size is large (n is greater that or equal to 30), use z-test.
